SPECIFICATION forming part or Letters Patent No. 651,553, dated June '12, 1900.

' Application filed July 25, 1899. Serial No.725,037. (No model.)

Be it known that I, ALEXANDER W. Mo- ARTHUR, a citizen of the Unitedv States'of America, anda resident of the city and county of Philadelphia, State-of Pennsylvania, have invented certain new and useful Improvements in Advertising Devices, of which the following is a specification. 1

My invention has reference to advertising devices; and it consists of certain features fully set forth in the following specification and accompanying drawings, forming part thereof.

The object of my invention is to provide a portable advertising device adapted to be moved over streets and to have numerous cards of different advertising firms exposed to View.

It consists of a cylinder rotatably supported on a frame and mounted on wheels. These wheels are arranged in the manner of a tricycle. There isa mechanical connection between the shaft carrying the wheels of the tricycle and the cylinder aforementioned. Air-engaging fans are carried by the cylinder, whereby the force of the wind can communicate motion to the wheels, and of course motion is communicated reciprocally to the cylinder by the rider of the tricycle through the mechanical connection referred to.

In the drawings like parts are referred to by characters of a corresponding kind in the different views.

Figure 1 is a general plan of the device with the tricycle-seat removed. Fig. 2 is a side elevation on a somewhat-reduced scale. Fig. 3 is a section on line A A of Fig. 1.

A is the cylinder. This cylinder in practice can be of a varying size adapted to the different specific needs to which it could be put as a carrier for advertising-cards.

B is an annular track. (Shown in Figs. 1

v and 3.) This track is supported on the wheels to a a through the frame fff. These members keep the said annular track in correct annular shape. There may be more braces called for in practice than the drawings show; but this is not material to my invention.

0 is an axle carrying the two rear Wheels aa.. This axle is journaled into the frame B at 0 C D is a primary bevel-gear carried by the axle O, and E is a bevel-follower fixed to the shaft F. G is a pinion carried by the said shaft.

The frame 71. h is carried by the fork and steering-post of the front wheel, and the frame fff is supported to the'frame h h by the barsff.

K K are teeth out on the lower edge of the cylinder A. The teeth of the pinion G mesh with the teeth of the said cylinder.

H H H H are a series of rollers carried by the cylinder A. These rollers run on the annular track 13. It will thus be seen that the sole support is the said rollers.

b and b are the foot-treads for theoperator of the tricycle.

|The handle-bar and other features of a tricycle are so well known that it is not thought necessary to make further reference to them here.

' m m m m m m m, &c., are a series of air vanes or wings. They are pivoted externally to the perimeter of the cylinder, as shown in Figs. 1 and 2. In the drawings I show these wings located at the upper port-ion of the cylinder. I of course do not confine my self to this location of the wings. In fact I do not confine myself to any specific location of them on the outer surface of the cylinder. It is sufficient that they are so located, Each of the wings m carries an integral lug n. This lug consists of a light extension, and when the fans are radially extended, as shown in the lower portion of Fig. 1, is adapted to contact with the body of the cylinder, and while the wind acts on the fans, as shown by arrow 3, Fig. 1, the said fan will maintain this position by reason of the said lug thus contacting, as is evident. When the wind, however, acts on the fans, as shown by arrow 1, the fans hug the surface of the cylinder, as shown in the upper portion of Fig. 1. 0' represents the radius of the extended fans and O the radius of the contracted ones. As the device moves forward or in the direction of the arrow 4, Fig. 1, the air striking the fans 'm 'm m, 850., in the manner already described will have the effect of rotating the cylinder A in the direction of the arrow 2, Fig. 1. Now the teeth K of the rotating cylinder communicate motion to the shaft F,and this shaft F transmits this motion to the shaft 0 through the bevels E and D. It therefore follows that the force of the Wind in actuating the cylinder in the manner described will assist the rider of the tricycle in his mission of propulsion.

In practice I would use wind-braces, so as to prevent the tilting of the cylinder. I, however, do not show such in the drawings.

The spaces marked No.1, No. 2, No. 3, and No. 4, &c., indicate spaces for the placing of advertisements. These, of course, extend all around the cylinder.

While in the drawings I show the connection between the axle and the cylinder as a geared one, yet I desire it understood that in practice I do not limit myself to this specific arrangement. I could use a friction connection with almost equal success. I therefore do not limit myself to the specific structure set out, but could make modifications without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination in an advertising device of a card-carrying cylinder, air-vanes adapted to be expanded or contracted automatically by wind action carried by the cylinder, a track-forming frame, rollers carried by the cylinder and adapted to run on the frame, thus supporting the cylinder thereon, traction-wheels for supporting said frame, a foottread with proper connections for actuating said wheels, an .axle to which said Wheels are affixed, a mechanical connection between said Wheel-axle and said cylinder, whereby on the operation of said traction-Wheels in the function of locomotion the said cylinder is 1'0- tated.
